There appears to be a broken transition in the north of the Starwood map; it's placed in the air, and even with considerable effort I could not use it. While it could very well be a quest area that I can't enter without a reason to, it gave me no indication towards this.
It's not a quest area, that's the transition to the Exile Camp, which for some reason was removed, just not fully. (I rather wish they'd put it back in.)
What? No. I don't think it ever went to the Exile Camp, it went to the crater that was removed as that plot had been concluded and I tried to trim out some extraneous areas as we've been adding so many new ones.
